Mount Polley Mine

  • open pit copper/gold mine
  • mill processes ~16,800 tonnes per day
  • commenced operations 1997
  • current mine life to 2026
  • concentrate trucked to Port of Vancouver

Mount Polley operations were suspended in May 2019, and the mine is on care & maintenance status. A resumption of operations is anticipated once the economics of mining at Mount Polley improve.

Extensive remediation work in the areas affected by the 2014 breach has been achieved during the past five years. The mine’s closure will not impact the ongoing environmental monitoring and remediation programs.

Mount Polley has an option to earn a 100% interest in seven mineral claims (3,331 ha), adjacent to the mine. Three target settings occur within the optioned claims and adjacent Mount Polley claims, including a potential northern projection of the high-grade Quarry zone beneath a post-mineral conglomerate unit, a partially tested glacial till covered area where regional magnetics suggests a faulted offset of the Mount Polley Intrusive complex, which hosts the Mount Polley orebodies, is present and a till covered prospective area immediately east of the Southeast zone. A deep looking 3-Dimensional Induced Polarization (IP) survey, along with a soil sampling program, was completed over the optioned claims, and a second deep looking IP survey is being undertaken over the historic mining areas at Mount Polley. This second survey will be used to help target deeper drilling in the mine site area, and as a guide in prioritizing the untested “new” anomalies in the optioned claim blocks covered by the first IP survey. Drill programs are being designed to test the targets outlined on the optioned claims and to expand the copper and gold resource near historic deposits, with a focus on gold rich zones.

Mount Polley is an open pit copper/gold mine with an underground component located in south-central British Columbia, 56 kilometres northeast of Williams Lake. The property encompasses 20,113 hectares, comprised of seven mining leases totalling 2,007 hectares, and 46 mineral claims encompassing 18,106 hectares. Mount Polley mine is owned and operated by Mount Polley Mining Corporation (MPMC), a subsidiary of Imperial.
